依赖错误：哎呀！看起来您没有安装 _plugins/lunrjs/jekyll_lunr_js_search.rb 或其依赖项之一

Question

使用插件jekyll_lunr_js_search 编译 Jekyll 项目时，在 windows 中总是出现以下错误。但是它可以在 gitlabci 上编译。

依赖错误：哎呀！看起来您没有安装 D:/myproject/_plugins/lunrjs/jekyll_lunr_js_search.rb 或其依赖项之一。为了使用当前配置的 Jekyll，你需要安装这个 gem。来自 Ruby 的完整错误消息是：'cannot load such file -- v8' 如果遇到问题，可以在 https://jekyllrb.com/help/ 找到有用的资源！

使用gem install jekyll-lunr-js-search时出现以下错误：

注意： 我已经安装了 python v2 和 v3 并且工作正常。使用py -2 测试的python shell 输出如下：

如果您查看 lib 目录，您会看到 ruby​​ 文件是 jekyll-lunr-js-search.rb 而不是 jekyll_lunr_js_search.rb。此外，它还可以作为 Rubygem 包使用。

只需将 gem 添加到 Gemfile 中的 :jekyll_plugins 组，运行 bundle install 并继续使用 Jekyll 构建/服务。
